I think you would be better served using a matrix HDMI switch to select the sources, assuming all sources are HDMI. If you are looking for both switching and upconversion of A/V sources, you may need to open up your wallet a bit.

Maybe it would be helpful to list your sources required and their connections. Also are you wanting the receiver audio just in one zone and the other zone's audio being served by the HDMI using the TV speakers?
